Three damaged Th350s in Row ?

I have put two rebuilt th350 trannys in and each got ate by a bad torque converter (I thought) that munched the pump. Then I had another highly reputable builder build a third t350 and HE installed it with a new torque converter, and the pump sounds fried again, that high-pitched screeching started right away, the one that gets louder as car is revved up. I don't know what is going on exactly. I do see what looks like a little bit of forward-to-backward movement at the flexplate and torque converter. The gap was perfect between the flexplate and the torque converter, just shy of 3/16. It's mated to a '69 Chevelle 350 motor that I took from my running '69 and put into my '71 Chevelle.
